Application February 23, 1954, Serial No. 411,785

2 Claims. (Cl. 254-26) The present invention relates to an attachmentfor the head of a carpenters claw hammer, the same being expresslydesigned and suitably constructed to appreciably increase leverage, thisin sucha manner as to facilitate greatly the pulling of nails,especially relatively long nails.

In carrying out the principles of the invention a spacing and fulcruminglock is provided, the same being effectually strapped on the centralportion of a hammer head, that surface of the block which contacts thetimber or other wooden or equivalent surface being cushioned to minimizethe likelihood of scarring or otherwise marring said surface andminimizing the likelihood of undue skidding, whereby the hammer may beaptly and satisfactorily rocked, all in a manner to permit the claw tofunction in dislodging and withdrawing the desired nail.

Another object of the invention is to provide a simple, practical andeconomical attachment which is readily applicable and removable andwhich is characterized by a compressibly resilient, but effectivelysolid rubber block, the fulcruming surface of the block providing thedesired are which makes it extremely easy to pull nails and whichobviates the possibility of the tapered ends of the claws of the hammercoming into contact with the wood surface.

Another object of the invention is to provide an attachment which merelyadds negligible weight to the over-all hammer and which may remainpermanently on the hammer after application, or is capable of beingremoved and set aside for handy use whenever necessary or desired.

Briefly summarized a preferred embodiment of the attachment ischaracterized by a compressibly resilient hammer-head fulcruming block,said block constituting a claw hammer attachment which functions toprovide increased leverage and assists greatly in the act of pulling andextracting relatively long nails comprising a compressibly resilienthammer-head fulcruming block, said block being generally wedge-shaped inside elevation and arcuately curved to provide a concave surface toconformingly contact a surface of said hammer-head and convex surface torest yieldingly against and fulcrum upon a work surface, and meanscarried by said block whereby it may be harnessed upon said head.

Further novelty is predicated on the construction set forth wherein thestated means comprises a pair of complemental U-shaped adapters whosearms and bight-portions embrace and are clamped upon cooperatingportions of said head, the free ends of the arms straddling and beingseparably fastened to said block.

Other objects, features and advantages will become more readily apparentfrom the following description and the accompanying sheet ofillustrative drawings.

In the drawings wherein like numerals are employed to designate likeparts throughout the views:

Figure l is a side elevational view showing a claw hammer with a handleappearing in part and showing the attachment applied and illustratingthe manner in which it Patented May 29, 1956 is used in pulling a nailout of a nail hole in a timber or an equivalent structure;

Figure 2 is a view in section and elevation taken on the horizontal line2-2 of Figure 1 looking in the direction of the arrows;

Figure 3 is a perspective view of the attachment by itse f;

Figure 4 is a section taken approximately on the plane of the line 4-4of Figure 3 looking in the direction of the arrows; and

Figure 5 is a view on a smaller scale based on Figure l and showing theposition of the claws of the hammer and the attachment when the clawsare first engaged with the head of the nail which is to be pulled.

In the drawings in Figure l, for example, the hammer is a conventionaltype and includes a handle 6 having a head 8 with the usual socketmember 10, poll 12 and arcuate claws 14. The work piece here underconsideration is denoted by the numeral 16 and the nail at 18. Theattachment for spacing and fulcruming and assisting in increasing. theleverage principle is shown satisfactorily, it is believed, in Figures 3and 4. As before stated a compressibly resilient solid rubber block 20is employed. This block in side elevation is generally wedge-shaped andit is arcuately curved. That is to say, there is a convex surface whichincludes a mounded heel portion 22 and a tapering portion 24 which ispositioned in the direction of the claws. The concave side 26 is of acurvature to fit against and therefore conform to the socket and clawportions of the hammer, as best shown in Figure 1. The block isgenerally rectangular in cross-section and therefore providessubstantially flat face parallel side surfaces. Embedded in each sidesurface is a wear and reinforcing plate 28. Each plate conforms ingeneral contour or shape to the shape of the block. The area of theplate, however, is such that when the plate is embedded, by molding orotherwise, the marginal edges thereof are spaced from the surroundingmarginal edge portions of the cooperating side surface. This providessatisfactory reinforcing and yet allows the projecting marginal portionsof the rubber to provide the desired elastic or yieldable properties.The plates are partially held in place by cooperating cross-pins 30which are best shown in Figure 4. These are at the respective forwardand rear ends of the plates and block and assist in stabilizing theover-all plate-equipped block. The outer surfaces of the plates areflush with the surrounding marginal portions 32.

There are two U-shaped adapters 34 and 36 and these serve to harness orstrap the block in its useful position on the head of the hammer in themanner shown in Figures 1, 2, and 5. Each U-shaped strap or adaptercomprises a suitably angled bight-portion 38 and spaced parallel arms4040. The free end portions of the arms straddle the block and aresuperimposed against the metal plates. These free end portions arebolted in place. Each bolt preferably includes a hollow stem or socketmember 42 and a screw-threaded member 44 which telescopes and screwsinto it in the manner shown. These are well known types of fasteners andserve aptly and satisfactorily in joining the respective arms to theblock and plate at the desired longitudinally spaced points. Thesefasteners are sometimes referred to as telescoping type screws. Thesteel plates provide satisfactory anchorage for the U-shaped adapters.In addition, however, these plates are for security for the rubber blockinasmuch as they are recessed into the side surfaces of the block andcannot scar or score the work surface.

The construction of the attachment is such, from a standpoint ofsimplicity and appropriateness, that a clear understanding of thedetails can be had from the disclosure herein provided. The method ofapplying and removing the attachment and its mode of use need not, it isbelieved, be set forth more explicitly.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling Within the scope of the appended claims.
